COLD REGIONS SCIENCE AND ENGINEERING PART Ⅲ, SECTION A3c BLOWING SNOW

摘要

Simple measures for the control of blowing snow, notably snow fences, have long been used, but the methods currently available for abating the nuisance of blowing snow (or even turning it to advantage) are far from adequate in a period of increasingly vigorous human activity in snow-covered regions. Fortunately there are in progress numerous studies which should lead to an early improvement in the situation. Field studies are yielding data which clarify the physical situation, while the general theory of two-phase flow (1. e. , fluids and solid particles) is exciting interest in a number of technical fields. Finally, techniques for the execution and interpretation of model and prototype investigations on drift control measures are being refined.
